WALTER W. TODENWARTH, OF ROSELLE, NEW JERSEY, ASSIGN'OB 0F ONE-HALF TO CLARENCE E. PRYOR, OF JERSEY CITY, IJEYV JERSEY. I Y I HYDRO-CABBON-BURNER.

Application filed. May 15, 1919.

To all whom it may concern Be it known that I, WALTER lV. TODEN- \VARTH, a citizen of the United States, and residing at Roselle. in the county of Union and State of New Jersey, have inventedcertain new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to hydrocarbon burners of the class used in stoves, ranges, furnaces and other heaters, and the object thereof is to provide an improved device of this class which is simple in construction, efficient in operation and comparatively inexpensive; a further object being to provide a hydrocarbon burner pf the class and for the puropse specified which may be easily controlled and by means of which the highest possible degree of heat in proportion to the fuel consumed may be obtained.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure 1 is a sectional side View of my improved burner;

Fig. 2 a plan view on an enlarged scale with part of the construction broken away; and,

Fig. 3 a sectional side view on the same scale as Fig. 2 and at right angles to Fig. 1.

In the practice of my invention as shown in the drawing, I provide a base a which is preferably pan-shaped in form and provided with legs'a and in the bottom of which is a longitudinal receptacle a designed to receive any suitable fibrous material to serve as an initial burner.

The base a is also provided centrally thereof and also centrally of the receptacle a with transverse raised supports a and arranged transversely of the base and integrally therewith is a frame member a having a transverse head portion (4 provided centrally with a tubular portion or sleeve a.

I also employ a burner head 5 which is circular in form, in the construction shown, and which comprises a main central burner plate 6 below which are supplemental burner plates Z2 which, in the construction Specification of Letters Patent.

Serial No. 297,253.

shown, are three in number, and said supplemental burner plates are of less diameter than the main central burner plate and above the main central burner plate Z9 are supplemental burner plates 6* which are also three in number, and less in transverse dimensions than the main burner plate 6 and greater in transverse dimensions in the construction shown than the supplemental burner plates 6 and the burner plates 6 and 6 are connected by vertically arranged rods 5 The burner plates 5 and b are annular in form and thisforms in the burner head a top chamber and a bottom chamber and the central burner plate 5 is provided with a central port or passage 71 controlled by a valve 5 having a threaded stem 5 passed through the top burner plate 6 and provided with a milled head o The burner plates b 25 and b, with the exception of the top plate I), are provided on their upper surfaces with small raised knobs or projections 6 by which said plates are separated so as to form thin annular burner slits 6 and the top burner plate 6 is provided with a plurality of circularly arranged apertures b which also form burners and over which are placed or supported a circular or ring-shaped deflector 6 the bottom burner plate 6 at the bot tom of the burner head 6 is provided centrally with a tubular sleeve 5 which passes downwardly through the sleeve a of the frame a of the base a, and said sleeve is provided with a set screw 0 which bears on the sleeve 6 and by means of this construction the burner head 6 may be adjusted vertically as will be readily understood.

A vapor tube (Z is arranged longitudinally of the base a on the supports a and provided with a small burner orifice (Z and detachable cap (Z and said vapor tube (Z is provided with an upwardly directed supply tube extension (Z preferably composed of two parts as shown connected at (Z and passing into the base a is an oil or hydrocarbon supply pipe 0 which passes through coupling members 0 connected with the base a, and said pipe 6 is provided with an upwardly directed extension 6 parallel with the burner supply tube (Z and connected therewith by brace members 6 any desired number of which may be employed, and

Patented Apr. 13, 1920.

employed in connection with the burner head 5 is an annular retort tube f, the normal position of which is just above the main central burner head plate 6 and said retort tube 7 is open at one side and the ends of the side portions thereof are connected with the pipes (Z and e at The retort f and the tubes (Z and e are,

in the construction shown, filled with fine wires or strips f composed of aluminum or other metallic substance, and the object of which is to regulate the flow of the hydrocarbons in gaseous or other forms through said parts and also to aid in heating the hydrocarbon in the retort f.

The operation will be readily understood from the foregoing description when taken in connection with the accompanying drawing and the following statement. It will be understood that the hydrocarbon supply pipe 6 is provided with the usual control valve, and the position of the parts of the burner shown in Figs. 1 and 3 may be considered as the normal position, and in the use of my improved burner it is set into the fire-box of a stove, range, furnace or other heater and takes the place of other sources of heat such as coal or wood. In starting the burner the valve in the supply pipe (2 is opened and the oil is allowed to flow through the pipe member 6 the retort f, and the pipe member (Z into the vapor tube (Z and a small amount of alcohol or a volatile hydrocarbon is placed in the receptacle a to saturate the fibrous material therein, and this fibrous material is ignited and serves to give the vapor tube (Z an initial heat and to convert the hydrocarbon therein into vapor which is discharged into the sleeve 6 of the burner head 6 through which it passes into the chamber (Z from which it passes out through the annular burner orifices I) and may be ignited, and the flame from the burner orifices 6 pass up around the main central burner plate 6 and around the retort tube 7, and said retort tube is highly heated as will be readily understood, and the vapor produced therein is carried to the vapor tube (Z and discharged into the sleeve 7) through which it passes back to the burner head and a constant supply of vapor is thus produced and the operation of the burner head will be continuous and automatic.

It will be understood that either the bottom chamber 6 of the burner head or both said. chamber and the top chamber 7) may be employed by means of the valve 6 or the manipulation thereof, and when the valve Z) is open the vapor passes into both of said chambers and out between the burner plates 6 and the burner plates 2), and the flame from the burner orifices 6 between the plates 6 strike the retort tube f directly and said retort tube is highly heated and the vapor produced therein and carried to the tube (Z constitutes what may be called a fixed gas, and in this way the highest possible degree of heat may be obtained.

When the top chamber 6 of the burner head is employed the vapor also passes out through the burner orifices b of the top plate 5 and the annular flame thus produced strikes the bottom of the annular deflector 6 and said flame is broken up and deflected both inwardly and outwardly over the cen tral portion of the burner head and over the retort f, and this also serves to increase the degree of heat produced and increase the vaporization of the hydrocarbon in the retort f.

It will also be seen that by the vertical adjustmentof the burner head herein described, the position of the sleeve 6 with reference to the vapor tube (Z and the position of the burner head with reference to the retort 7 may be adjusted and the operation of the device thus controlled to an extent.

The arrows in Fig. 3 will show the direction of the various flames or flame sheets produced by the burner head under different conditions and the vapor supplied to the burner head may be limited to the bottom chamber 6 and the flames or flame sheets produced will be directed outwardly beneath the central plate 6 of the burner head and will serve to heat the retort 7 only to the degree necessary to supply the burner with vapor, and to produce a moderate degree of heat in the stove, range, or other apparatus in connection with which the burner is employed, or the said burner head may be controlled so as to highly heat the retort or to heat said retort to any desired extent, and in this way a very high degree of heat may be produced.

With my improved burner the entire firebox of an ordinary stove, range, or similar heater can be filled with flame heated at a very high degree of temperature and the divisional construction of the burner head provides means whereby a part of the capacity of said heat may be employed whenever desired, or the entire capacity thereof when necessary.

I also provide means for keeping the burner orifice (Z in the burner tube (Z clean, comprising a rod g mounted horizontally in the base a and provided at its outer end with a head 9 by which it may be manipulated, and said rod is provided at its inner end with an arm 9 having at its end a pin g and by turning the rod 9 the arm may be thrown into the position shown in Fig. 3, in which operation the pin g will pass into and through the orifice (Z in the vapor tube (Z and clean said orifice.

It will also be understood that the size, or capacity of the burner head Z) may be increased or decreased by increasing or decreasing the number of burner plates 5 and 0*, and said burner head may be of any desired transverse dimensions, and while I have shown and described the preferred construction for carrying my improvement into effect, my invention is not limited to the details of construction herein shown and described, and changes therein and modifications thereof may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages.
